This invention relates in general to projecting machines and. moreespecially to machines for projecting news items such as stockquotations on ticker tape and the like.

Among the objects of the present mvention it is aimed to provide animproved construction which makes possible the use of a single mirrorfor projecting the images on a vertical screen above the projectingmachine,

in which construction the ticker tape is freeto be inspected as itleaves the ticker machine and before it passes to the'projectingmachine.

Among the objects of the present invention it is also aimed to providean improved mechanism for dissipating the vibrations transmitted to thetape by the ticker so that the tape may pass the projecting lens in acomparatively uniform even feed.

The present invention also aims to provide an improved construction forcontrolling the operation of the motor for driving the tape drawing orpulling means contemplating an electric make and break which is spaced aconsiderable distance from the tape, which has no open spark, and whichwill produce a dwell both before making contact and before breakingcontact in order to protect the tape from the jar incident to the suddenstopping and starting of the movement of the tape.

The present invention also aims to provide an improved mechanism forcontrolling the rewind action of the tape after it is discharged fromthe projecting mechanism whereby the jacent to the rewind reel.

These and other features, capabilities an advantages of the inventionwill appear from the subjoined detail description of one specificembodiment thereof illustrated in the -1 accompanying drawings in whichFigure 1 is a front elevation partly broken away of a device equippedaccording to the present invention;

Fig. 2 is a side elevation partly broken 59 away of the deviceillustrated in Fig. 1;

Fig. 8 is a plan of the rewind mechanism shown in Fig. 7.

In the embodiment shown in Figs. 1 and 2, there is provided a frame 1having a lower platform 2 and an upper platform 3.' On the platform3there is supported the lamp housing 4 containing the lamp 5 and lens 6through which the rays from the lamp 5 pass to the inclined mirror 7 andbywhich mirror 7 the light rays are deflected upward through a lightaperture across which the tape T passes.

The tape T is preferably composed of a transparent material or atranslucent material so thatlight may readily pass through such tape andproject images of the characters on the tape to the projecting lensformed in the housing 8 from which the images are projected onto themirror 9 in the frame 10 and deflected by such mirror 9 onto thevertical screen 11. The frame 10, supporting the mirror 9 and screen 11,may be supported above the projecting mechanism in any usual way. In thepresent instance, the brackets 12 are provided which are secured to thewall 13 on which the frame 10 rests. 7

On the platform 3 adjacent to the lamp housing 4;, there is alsoprovided a supporting member 14 for supporting the ticker generallydenoted by the reference character 7 15, which is provided with thefeeding means consisting of the feed rollers 16 and 17 which cooperatewith the printing wheel 18 in the usual way. The tape T passes from thesupply reel 19, see Fig. 1, to the feeding means 16, 17, and then pastthe printing means 18. The reel 19 is supported on the shaft 20extending from the bracket 21 which is connected to the supporting frame14. From the printing mechanism 18, the tape passes over anssurnthefinger 22 to the angle plate 23 which has guiding projections 24, 25,extending upward- 1y, between which the tape passes to the curvedportion 26 and then between the downwardly extending guiding projections27, 28, to and along the lower face of the frame 29 to the idler 30, andover the idler 30 down to the feed roller ,31 beneath the platform 3 tothe rewind reel 32.

In order to dissipate the' vibrations transmitted to the tape T by theticker 15 due to the intermittent feeding action of the feed means 16,17, and printing mechanism 18, there is provided a friction creatingdevice known inthe projecting machine trade as an ironing out devicewhich consists of the lever 33 extending through the yoke 34 andadjustably connected thereto by the screw 35. This yoke 34 is pivotallyconnected to the bracket 36 which is secured to the lower face of theplate 37 extending from the upper end of the lamp housing 4 adjacent tothe ticker 15.

One end of the lever 33 is preferably provided with a tape engagingdevice 38, and the other end extends through a weight 39 which isconnected to the lever 33 preferably by means of a screw 40. By means ofthe screws and 40, both the length of the arms of the lever 33 may beadjusted and the position of the weight 39 adjusted in order to obtainthe degree of pressure desired on the tape T. The tape engaging device38, as

shown in Fig. 3, preferably engages the tape T to press it against thelower face of the frame 29 before the tape passes to the light aperture41 in the frame 29.

The frame 29, as shown in Fig. 3, is provided with the light aperture41, the tape passing across such light aperture 41 to permit the lightrays defiecte'd'by the mirror 7 to pass through the tape to theprojecting lens in the housing 8. The frame 29, as shown in Fig. 3, ispreferably hinged at 42 to the top of-the lamp housing 4 and is adaptedto fol'd down over the path of movement of the tape T to be engaged bythe projection 43 formed at the upper end of the arm 44 secured to thefront face of the lamp housing 4, see

Figs. 1 and 2.

On the platform 2 there is supported th motor 45 which is operativelyconnected to actuate the drawing ro ler 31 and the rewind reel 32. Thetape pulling roller 31 and rewind reel 32 are adapted to be stopped andstarted according to the operation of the ticker 15. In order so tocontrol the operation of the tape pulling roller 31 and rewind reel 32,the motor 45 is operatively connected to a mercury switch 46 which inturn is operatively connected by means of the connecting link 47 withthe lever 48 which is pivotally connected at 49 to the side of the lamphousing 4 adjacent to the ticker 15. The lever 48 is preferably providedwith a tape engaging sheave 50 which rests on the upper surface 1,9oasoeof the tape T to deflect the tape T to form a loop or bend before theytape T engages the bent plate 23. v The mercury switch 46 is supportedon a plate 51 which is pivotally mounted on the projections 52, 52.

The connecting link 47 has an extended slot 53 at its lower end throughwhich extends the pin 54 on the plate 51 and a slot 98 to receive thepin 99' of the lever 48. The pin 54 is so positioned relative to thepivotal connection of the plate 51 with the projections 52, 52, that thecenter of gravity of the plate 51 with its appurtenant parts is disposed between the projections 52 and the pin 54 so that the plate 51will tend to exercise a downward pull on the connecting link 47 when theend of the plate containing the pin 54 is raised by the connecting link47. The center of gravity of the plate 51 relative to the projections52, 52, is also such that when the link 47 does not exercise an upwardpull on the plate 51, the end of the plate containing the pin 54 willdescend to its lowest point determined by the face 55 of the member 56.

The mercury in the tube 57 of the mercury switch 46 relative to itscontacts is so disposed that the contact will be broken when the end 58of the tube 57 is raised and that contact will be made-when the end 58is lowered. The mercury switch 46 is connected to the rheostat 59 bymeans of the conductor 60, which rheostat 59 by means of the conductor61 is connected to the main lead 62 leading to the outlet plug 63. Theother end of the switch 46 is connected by the conductor 64 to theconductor 65 of the motor 45. The other pole of the motor 45 isconnected by the conductor 66 to the conductor 67 by means of which itis connected to the other main lead 68 of the outlet plug 63.

The motor 45 is provided with a shaft 69 on which is mounted the sheave70 which .is connected by means of the belt 71 to the sheave 72 on theshaft 73, which is provided with a worm 74 in mesh with the worm wheel75, which worm wheel 75 is mounted on the shaft 76, which shaft 76 hasmounted thereon the sheaves 77 and 78. The sheave 77 is connected bymeans of the belt 79 to the sheave 80 on the shaft 81 journaled in theupper end of the bracket 82. On the shaft 81 is mounted the tape pullingroller, 31. In order to frictionally engage the tape T with the tapepulling roller 31, the idler 83 is journaled in the upper end of the arm84 which is pivotally connected at 85 to the bracket 82, which arm 84has an extension 86 to receive an adjustable weight 87 whereby thepressure on the tape T or frictional engagement between the idler 83 andthe tape pulling roller 31 can be properly adjusted.

The sheave 78 is connected by the spring belt 88 with the sheave 89 onthe shaft 90, on which shaft 90 is mounted the reel 32.

From the foregoing it will appear that and as a result thereo when theticker 15 is operating to form sufiicient slack to permit the sheave 50to depress the tape T low enough to permit the connecting link 47 inturn to permit the end 58of the mercury switch 46. to be depressed,contact will be made to permit the motor 45 to be actuated in turn toactuate the tape pulling roller 31 and reel 32. It will also appear thatas soon as the ticker 15 pauses sufficiently long to permit the tapepulling roller 31 to cooperate with the ticker 15 to dissipate the slackin the tape T and thereby raise the lever 48, in turn to raise theconnecting link 47, the end 58 of the switch 46 will be raised to breakcontact and thereby cause the motor 45 to be stopped.

In a period of five minutes the ticker. 15

may be started and stofpped a number of times, the motor stopped andstarted a number of times. In order to protect the motor 45 frombeingoverheated by the constant stopping and starting of the same, therheostat 59 will function to diminish the amperage sufiicient to preventsuch overheating.

It will also appear from-the foregoing that due to the slot 53 at thelower end of the connecting link 47, the motor 45 can by no possiblechance be stopped simultaneously with the stopping of the ticker 15,but, on the other hand, always a little after the ticker 15 has stoppedand thus protect the tape from the jar to which it would be subjected ifit were suddenly stopped, especially if the ticker 15 and motor werestopped at the very same of the switch 46 to be lowered to make contactand start the motor 45.

45 will not acquire its full momentum until Since the motor after it hasmade a number of revolutions, during the period that further slack isbeing formed in the tape T, that is while the.connectin'g link 47 dropsits fullest extent afforded by the length of the slot 53, sufiicienttime will have elapsed to permit the motor to acquire its full operatingmomentum. In this way, the slack in the tape T can never mount up, itbeing assumed, of coursepthat the speed of the motor 45 will be timed tosynchronize substantially with the rate of feed provided by the feedingmeans 16, 17.

d The spring belt 88 is provided in order to compensate for thegradually increasing drawingac'tion transmitted to the tape T by thegradually increasing diameter of the rewind reel. It will be noted thatthe uniform feeding roller 31, constituting the tape draw ing roller, isinterposed between the project-' ing mechanism and the rewind reel 32 sothat the uneven drawing action, or gradually 1ncreasing drawing action,of the rewind reel In such case, however, it is desirable also todiminish the drawing tension produced by the rewind reel 32. This isvery effectively done by providing a brake to anchor the rewind reel 32against rotation, at least sufiicient to permit the spring belt 88 toslip relative to the sheave 89. T 0 this end, the reel 32 is providedwith a braking drum 91 to be engaged by a brake. shoe 92, which ispivotally mounted on the arm 93 extending from the bracket 94 oftheihousing 95 of the worm wheel 75. .The brake shoe 92 is provided withan arm96 having a finger 97 to engage the time T, as indicated in Fig.7. In this instance, when the ticker 15 stops and the rewind reel 32continucsto wind up the ta T, itwill take up the slack in the tapebetween the tape pulling roller 31 and the rewind reel 32 to raise thefinger 97 and thereby cause the brake shoe 92 to'be wedged against thebraking hub 91.

It is obvious that various changes and modifications may be'made to thedetails of construction without departing from the general spirit of theinvention as set forth in the appended claims.
